Dispositivo de protección contra corrientes residuales electromagnético serie CQL14
El CQL14 is specified for residual-current protection without overcurrent protection. Select it using the published voltage, current, pole and protection data, then confirm conductor coordination, fault conditions, enclosure requirements and local installation rules.
Descripción del producto
CQL14 is a electromagnetic residual current device for AC 230/400V applications. It is intended for residential, commercial and industrial circuits where a separate overcurrent device is coordinated; this describes an evaluation context, not a universal approval. Confirm the complete circuit design before specifying the product.
residual-current protection without overcurrent protection is distinct from adjacent protection functions. Do not infer AC/DC suitability, residual-current protection, automatic control or isolation performance from the product family name alone.

CQL14 Product FAQ
What is the CQL14 used for?
The CQL14 is specified for residual-current protection without overcurrent protection in AC 230/400V applications, within the ratings and configurations listed in its technical table. Final suitability depends on the complete circuit design.
How does the CQL14 work?
Its operating principle follows the documented function: residual-current protection without overcurrent protection. Use the exact model documentation for thresholds, timing, trip behaviour, terminals and test procedures.
How do I choose the CQL14 rating and poles?
Start with the design current and system arrangement, then choose only a published option. The page lists pole options as 2P / 4P; confirm neutral, polarity, conductors and isolation requirements.
What safety limitation applies to the CQL14?
Do not treat the CQL14 as a universal substitute for another device. Confirm 30mA, 100mA or 300mA options, the system voltage, fault or leakage conditions and any separate upstream protection before selection.
Can the CQL14 be used in another circuit type?
Only when the exact ordered configuration is rated for that circuit. AC and DC duties, residual-current devices, isolators, smart controls and voltage protectors are not interchangeable by appearance or current rating.
How should the CQL14 be installed and tested?
Use the exact product drawing, terminal identification and instructions. A qualified person should verify isolation, conductors, torque, settings, coordination and functional tests before energising the circuit.
Confirm the Right CQL14 Configuration
Send the model, rating, poles, system voltage, application, quantity and document requirements. CHAC will review the request against the published data.
